google/gru: Fix up PWM regulator ranges

We did yet another small adjustment to the PWM regulator ranges for
Kevin rev6... this patch reflects that in code. Also rewrite code and
descriptions to indicate that these new ranges are not just for Kevin,
but also planned to be used on Gru rev2 and any future Gru derivatives
(which as I understand it is the plan, right?).

BRANCH=None
BUG=chrome-os-partner:54888
TEST=Booted my rev5, for whatever that's worth...
